What makes you think all phones have unique numbers? Some have no direct dial numbers.
As for each device getting a unique IP address this is somewhat in the spec for EUI-64 IPv6 address. Your IP is based on your interfaces MAC address but this becomes a privacy nightmare.
If the MAC address’s of the wifi chip in your phone is 1122.3344.5566 your IPv6 address at home can be 2001:0db8:0000:00000:1122:33ff:fe44:5566 but when at work your address may be 2001:db8:1000:0000:1122:33ff:fe44:5566. No matter where you connect to the last 4 sections of the address is the same and companies will use that as one of the data points of your digital profile.

I meant “in the same way that phone numbers are unique to phones (not perfectly unique, some phones have dual Sim, some have no sim, sometimes a Sim changes numbers after contacting the provider, etc)”
Its just typing all that^ in a title is kinda long.
EUI-64 IPv6 (and why its not a reality) though is kinda what I’m curious about. But not really because, even under that spec, its still a MAC address. Its not static like a phone number. I want to know why networks were not created in a way where I can send a message to a laptop regardless of what WiFi its connected to (assuming it is connected and online).

Because it will be an ungodly thing to manage. The national phone databases are already a nightmare to manage. it would be far worse if we had a global one.
